That's like a living ward, the skill is very OP tho but meh the rest of sages, I'm not too happy about.
I don't think you wanna go full str, unless you literally wanna ''miss'' every hit, thus why I put ''hybrid guard''
To you guys, money Always helps and one could argue that getting to endgame gear a lot faster than non donators will make you OP (for awhile) since you have a higher lvl, higher tier gear etc. The big difference with Jainus etc is that you can farm pretty much everything in game yourself as well without charging insane amounts. It will take a long time but you can. If you couldn't that would be truely P2W.
For everyone saying ''in the future they'll update the IM and make everything P2W'' I say, Chill bruh, so far so good. Enjoy it as long as it lasts and don't create doom scenarios when they are not imminent.
